The method of preparing Ethyl-2- (Ethylthio) -6, 7-Difluoro-4-Hydroxyquinoline-3-Carboxylate is very delicate. The method is often made from a specific starting material through several delicate reactions.
At the beginning, a suitable fluorine-containing aromatic compound is selected and ingeniously combined with a sulfur-containing reagent. This step requires fine regulation of the reaction conditions, such as temperature, solvent and catalyst selection. If the temperature is too high or side reactions occur, if it is too low, the reaction will be delayed and the desired effect will not be achieved. The selection of specific organic solvents, such as aprotic solvents, can promote the reaction and enhance the solubility and reactivity of the reactants. The clever use of catalysts can significantly reduce the activation energy of the reaction, speed up the reaction rate and increase the yield. < Br >
Then, the core structure of quinoline is constructed by cyclization reaction. This process requires strict requirements on the reaction environment, and the pH and reaction time need to be accurately grasped. Improper pH can easily lead to wrong cyclization check points or incomplete cyclization. If the reaction time is too long, it may cause excessive reaction and destroy the structure of the product; if it is too short, the cyclization will not be completed, and the product will be impure.
Subsequent, the carboxylethyl ester group is introduced at a specific position, and this step also requires fine operation. With the help of suitable esterification reagents and reaction conditions, the group is accurately integrated and damage to the existing structure is avoided.
After each step of reaction, it needs to be separated and purified to remove its impurities and obtain a pure product. Commonly used methods include column chromatography, recrystallization, etc. Column chromatography is separated according to the polarity difference of the substance, and recrystallization is purified by different solubility. After these steps, Ethyl-2- (Ethylthio) -6, 7-Difluoro-4-Hydroxyquinoline-3-Carboxylate can be obtained. This synthesis method requires careful study of the details of each step of the reaction to obtain the ideal product.
